Abstract: 【OBJECTIVE】Optimizing the method of fertilizing for plant roots is the key strategy for high profitable production【METHOD】The effect of root-divided fertilization on plant growth and fruit yield was investigated using cucumber cultivar “Jinlvluyou” and “Zhongnong 203” as materials【Result】In the treatment of standard solution +1/2 standard solution for each half of root zone there was no significant reduction in total plant fresh weight and fruit yield although total quantity of fertilizer was reduced by 25%; in the treatment of 2 standard solution +water and that of 1.5 standard solution +0.5 standard solution total plant fresh weight was significantly increased by 23.2%and 16.6%, and fruit fresh weight was significantly improved by 34.2%and 27.1%,respectively, though total quantity of fertilizer was constant【CONCLUSION】It concluded that it could save fertilizers or improve the plant growth and fruit yield by root-divided fertilization in cucumber.
